comrotmn TOOL.

Application filed April 4,

To all whom it may concern:

Be it known that I, JEROME J. MILLER, a citizen of the United States,and a resident of Chadron, in the county of Dawes and State of Nebraska,have invented certain new and useful Improvements in Compound Tools, ofwhich the following is a specification.

My present invention relates generally to compound tools, and moreparticularly-to a device having for its primary function the sharpeningof pencils and at the same time cleaning and scraping the finger nails,my object being the provision of an implement of this general naturecapable of effectively utilizing old safety razors and the like wherebyto insure a keen cutting edge, and having means to detachably hold sucha blade in order that it may be readily and easily changed from time totime as the condition of its cutting edge or edges renders the use of anew blade desirable.

As a. pencil sharpener my invention proposes a body having side grippingfaces whereby it may be readily held between the thumb and forefingerand having a blade receiving surface together with an undercut shoulderalong one or both sides of its surface, the shape of the latterpreferably necessitating fiexure of a blade, and further proposes anarrangement wherein this body has a lengthwise tapering bore adjacent toone side of the blade receiving surface and opening therealong andtherethrough adjacent to the undercut shoulder, a portion of the latterof which is removed for the major portion of the length of the boreso asnot to interfere with the cutting operation u on insertion of a pencilwithin the bore an itsrotation against the cutting blade.

As a convenient implement for cleaning and scraping the finger nails myinvention proposes an extension in connection with the body below itsblade receiving surface so disposed that a blade properly located on thesurface will overlie the extension, this extension having side groovesthrough which a finger nail may be-passed against the cutting edge ofthe blade, and also having extending scraping lips at one side of thenail receiving groove adapted to extend beneath the nail and clean thesame while it is scraped against the blade edge.

In the accompanying drawing which illus- 1923. Serial No. 629,871.

trates my present invention and forms a part of this specification, I

Figure 1 is a perspective view of the tool as a Whole,

Figure 2 is a top plan view thereof,

Figure 3 is a vertical cross section taken substantially on line 3-3 ofFigure 2, and

Figure 4 is an end view showing a slightly modified form.

Referring now to these figures and particularly to Figures 1, .2 and 3my invention proposes an implement including a body generally in theform of a rectangular block 10, provided with oppositely disposedconcave portions 11 at the sides thereof, which concave portions arepreferably knurled as shown in order that the implement as a whole maybe readily grasped and held between the thumb and forefinger in use.

In its upper and lower faces, the block 10 is provided with bladereceiving surfaces 12, and along opposite sides of these surfaces areundercut shoulders 13 so that a blade of the double edge type indicatedat 14 will, when dispose-d upon a blade receiving surface, have itsopposite cutting edges securely held beneath the undercut shoulders, itbeing contemplated that the blade receiving surfaces will be curved,preferably convexly curved as shown in Figures 1, 2 and 3 although thiscurvature may be concat e as indicated at 15 in Figure 4. It is alsocontemplated that at spaced points along the centers thereof, the bladereceiving surfaces will have threaded bores for the reception offastening screws and'the like 16 for passage through the blades 14disposed thereon, although while apparently vnecessary in the case ofthe concave surfaces 15 of Figure 4, these fasteners 16 are notessential to the support of the blade 14 upon the convex surfaces as inFigures 1, 2 and 3.

Lengthwise thereof and extending therein from one end, the block 10 haspencil receiving and guiding bores 17 arranged so as to open for thefull length thereof through the blade receiving surfaces immediatelybeneath the undercut shoulders 13, the latter of which are cut awayintermediate their ends as at 18 for the major portion of the lengths ofthe pencil receiving and iding bores 17 so as not to interfere with t efree cutting of the pencil as it is rotated within any one of the boresagainst the adjacent edge of the blade 14 and so as not to interferewith the free discharge of the chip. lin these various respects exceptas to the mere curvature of the blade receivin surfaces, the implementof Figure 4 is lifie that of Figures 1, 2 and 3.

' For the purpose of cleaning and scraping the finger nails, the block10 has an extension 19 at one end, between the blade reeeiving surfacesso disposed that the blade will at one end overlie the upper and lowerfaces of such extension and will particularly overlie at their sidecutting edges the side grooves 20 with which this extension is formedfor the purpose of receiving the finger nails, and in order that thefinger nails may thus be guided transversely across the blade edges andbe scraped thereby. Along the outer sides of its grooves 20, theextension 19 has outstanding lips-21 adapted to extend beneath thefinger nail as it is moved within the adjacent groove 20 in order thatthe nail may thus be cleaned as it is scraped.

lit is 'to be noted in particular'that my invention is thus adapted toutilize discarded safety razor blades, more especially those of thedouble edge type, and to receive and support such blades in a manner sothat the suficiently keen edges thereof will'be presented for thecutting of the wood and lead of pencils during the sharpening operation,and also in such manner that the blades, when becoming too dull for thepurposes of the invention, may be readily removed and other bladessubstituted therefor.

I claim:

1. A pencil sharpener including a body having a pencil receiving andguiding bore and a blade receiving surface along and through one side-0fwhich the bore opens, said body having undercut shoulders at oppositesides of its said blade receiving surface, cut away intermediate theends thereof glon'g the ma orportion of the length of said ore.
